Why do shepherds laugh at bullfighting?

There is a Chu Shi who loves painting and calligraphy in Sichuan. He has hundreds of paintings and calligraphy in his collection. One of them is a cow painted by Dai Song, which is very precious. He sewed a painting sleeve with brocade and made a painting shaft with jade, and he always took it with him.

One day, he spread out his calligraphy and painting to bask in the sun. A shepherd boy saw the cow painted by Dai Song, clapped his hands and said with a smile, "This painting is for bullfighting! The power of bullfighting is used in the horn, and the tail is tightly sandwiched between the legs. Now the cows in this painting are wagging their tails and fighting, which is ridiculous! " Du smiled and thought what he said was very reasonable. There is an old saying: "Ask the farmer for farming and the maid for weaving." This truth will not change!
